I've got about 15 pieces of 9mm brass that have been once fired, when I resized them the die punched the bottom of the primer out but left the outer rim of the primer stuck in the primer pocket. These cases were part of a larger batch that all had crimped in primers but they punched out fine.
Anyone come across this before and have a way of dealing with it? I'm gonna try drilling the leftover primer rim out. I don't really need the brass but I'm one of those guys that likes tinkering when I find a problem
